I rarely post comments in user forums but regarding the Bricasti M1 I feel compelled to comment. For the past few months I have owned the M1 limited gold with built in ethernet interface and must say that it is simply the most elegant piece of electronics I have ever had. I have listened to the Berkeley reference dac and have owned the Empirical Audio Overdrive SX but the M1 with ethernet takes sound reproduction to an etherial level.
I would be up for a shootout between M1 with DLNA Ethernet and Overdrive SX with DNLA Ethernet. The Overdrive SX is a different animal now. Many upgrades to it. 20psec of jitter, Duelund caps etc..
